We have examined the usefulness of high vacuum techniques to synthesize primary amine-terminated polystyrene. End-capping living polystyryl lithium with 1-(3-bromopropyl)-2,2,5,5-tetramethyl-1-aza-2,5-disilacyclopentane using an appropriate amount of THF as cosolvent affords quantitative end groups as evidenced by MALDI-TOF MS. Efforts are currently underway to determine the effectiveness of the end-capping reaction under various reaction conditions as well as to further characterize PS-NH2 using 13C NMR spectroscopy.
